Question

Electric field lines for several objects are shown below.Which of these diagrams depict the proper rules of drawing electric field lines? Select all that apply.

Answer 1

The field lines are drawn properly for the diagrams A, B, D

What are the rules of drawing electric field lines?

There is no intersection or crossing of electric field lines. Intersections would indicate that the electric field is flowing in two distinct directions at a given point in space, which is not possible.

The force that a positive test charge would encounter at any given location is indicated by the direction of the electric field lines at that point.

Positive charges are the starting point of electric field lines, which end on negative charges. They show the path that a positive test charge would take in the event that it were dropped into the field.

Answer 2

We can use the following rules:

Lines begin and end only at charges (beginning at + charges, ending at - charges) or at Infinity.

Lines are closer together where the field is stronger.

Larger charges have more field lines beginning or ending on them.

The correct diagrams are:

Diagram A

Diagram B

Diagram D
